摘要

Background and Objectives: The association between black-colored foods (black foods) such as black beans, known for their high antioxidant capacity, and the prevention of metabolic diseases has been explored, but not in a large population. Therefore, this study examined relationships between the consumption of black foods and metabolic syndrome in Korean adults. Methods and Study Design: Data from 9,499 40-65-year old subjects (3,675 men and 5,824 women) from the 2010-2015 Korea National Health and Nutrition Examination Survey were used in the analysis. Black food consumption was estimated using 24-h dietary recall data, and analyses were performed according to black food consumer and non-consumer groups. Results: The average total consumption of black foods was higher in women than men. The total black food consumer group in women had a 24% reduced risk of abdominal obesity than the non-consumer group (p=0.007). Furthermore, waist circumference decreased significantly with an increase in total black food consumption in women. High consumption of total black foods and black beans reduced the risk of abdominal obesity by 26% (p for trend=0.012) and 29% (p for trend=0.003) compared with no consumption. No risk factors for metabolic syndrome were associated with black food consumption in men. Conclusions: In conclusion, black foods, including black beans, may have beneficial effects on metabolic syndrome components, especially abdominal obesity.
